Server module for SocketCluster
Minimal server module for SocketCluster
This is a stand-alone server module for SocketCluster. This module offers the most flexibility when creating a SocketCluster service but requires the most work to setup. The repository for the full-featured framework is here: https://github.com/SocketCluster/socketcluster
You will need to install
socketcluster-client (https://github.com/SocketCluster/socketcluster-client) separately.
To install this module:
npm install socketcluster-server
You need to attach it to an existing Node.js http or https server (example):
var http = ;var socketClusterServer = ;var httpServer = http;var scServer = socketClusterServer;scServer;httpServer;
var http = ;var socketClusterServer = ;var serveStatic = ;var path = ;var app = ;app;var httpServer = http;// Attach express to our httpServerhttpServer;// Attach socketcluster-server to our httpServervar scServer = socketClusterServer;scServer;httpServer;
Note that the full SocketCluster framework (https://github.com/SocketCluster/socketcluster) uses this module behind the scenes so the API is exactly the same and it works with the socketcluster-client out of the box. The main difference with using socketcluster-server is that you won't get features like:
* Note that the
socketClusterServer.attach(httpServer, options); takes an optional options argument which can have a
brokerEngine property - By default, socketcluster-server
sc-simple-broker which is a basic single-process in-memory broker. If you want to add your own brokerEngine (for example to scale your socketcluster-servers across multiple cores/hosts), then you might want to look at how sc-simple-broker was implemented.
The full SocketCluster framework uses a different broker engine:
sc-broker-cluster(https://github.com/SocketCluster/sc-broker-cluster) - This is a more complex brokerEngine - It allows messages to be brokered between
multiple processes and can be synchronized with remote hosts too so you can get both horizontal and vertical scalability.
The main benefit of this module is that it gives you maximum flexibility. You just need to attach it to a Node.js http server so you can use it alongside pretty much any framework.
